Snyk changed the following file(s):

• packages/tree/package.json

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

⚠️ Warning

Failed to update the yarn.lock, please update manually before merging.

🦉 Directory Traversal

[anaconda-security-bot]

This set of upgrades includes a major and high-risk architectural change to @jupyter-notebook/application, which is now based on JupyterLab components. The other upgrades are minor stabilizations.

High Risk

@jupyter-notebook/application from 0.0.0-use.local to 7.0.0
This is a significant major version upgrade that re-builds the Jupyter Notebook application on top of JupyterLab components. While the classic document-centric user experience is preserved, the underlying technology is completely different.

Breaking Changes:

• New Architecture: The application is now based on JupyterLab 4.0, inheriting its features and extension system.
• Extension Incompatibility: Classic Notebook v6 extensions are not compatible with Notebook 7. You must migrate to JupyterLab-compatible extensions.
• New Features: This version introduces many features previously available only in JupyterLab, such as a visual debugger, real-time collaboration, a table of contents, and theming with dark mode.

Recommendation: A full migration and testing plan is required. Verify that all necessary extensions have a compatible version for JupyterLab 4 / Notebook 7. Treat this as a major application migration.

Medium Risk

@jupyterlab/apputils from 4.6.0-alpha.3 to 4.6.0
This upgrade moves from a pre-release to a stable version. While typically consisting of bug fixes, final releases can include API adjustments not present in the alpha. The migration guide for this version range also notes a significant change for extension developers, replacing @jupyterlab/builder with @jupyter/builder for building extensions. The risk is medium due to potential final API changes and the notable build system update.

Low Risk

@jupyterlab/mainmenu from 4.5.0-alpha.3 to 4.5.0
This is a stabilization release from a pre-release to a final version. Changes primarily consist of bug fixes and minor enhancements, such as UI adjustments to menus and keyboard shortcuts. No breaking API changes are documented.
